No, my issue is sight fishing. For most of the year I sight fish to near exclusion of all else, but you can't expect it to work out that way in the winter. For the next couple of months sight fishing is the exception, not the norm.
Many of us carper lack confidence in blind casting. Sight fishing is not only more fun it is often much more effective. When we do try it, blind casting can quickly feel like a waste of time. Simply not true. Fight that feeling. That feeling is nothing but a projection of your own lack of confidence on reality.
Today I found myself on the water with one hour (no more, no less) to burn. No sun, no shallow carp and no time to change spots looking for the improbable. After 45 minutes fighting it I finally sighed deeply, tied on an Egan's Headstand and started ever so slowly working a deep back-eddy. It is easy to forget what comes next and it is really cool.
Nothing exists except the fly-line in your fingers and, incomprehensible twirls of the surface currents. Your soul slows. Your consciousness fades. And then out of the deep silence and mystery your line, rod and soul are suddenly brought suddenly and shockingly back into focus.
Incidentally, if you are looking to try blind casting for carp in a river I would recommend "Active Nymphing" by Rich Osthoff. I was excited when I found this book and bought it on the spot because it captures everything I do to work a fly blind for carp and more.
